TEXT:

The Glad-Grip started as a useful device to help connect and disconnect the hydraulic hoses on farm implements. This device is called the Hydra-Grip. As time passed and the Hydra-Grip became better known, several truckers saw the Hydra-Grip and thought they would be an asset on the air hoses of semi truck tractors. There is nothing on the air hoses to get a grip on except the hose itself or the spring below the glad hand. Especially during cold weather when drivers twist the glad hand loose from its mating coupler half, the hose would be bent at a severe angle causing the hose to either break or develop a leak. This problem is greatly reduced by installing the Glad-Grip, a very durable and simple handle. Safety is also a factor as the operator's hand is not in contact with the air hose itself.

The Glad-Grip has a machined steel core designed and tested to withstand a minimum of 3000 psi of hydraulic pressure, far in excess of the pressure on the air line system. The center bore of the core exceeds DOT requirements of at least 66% of the air l ine inside diameter. The threads, both male and female, are cut to American National Standard Institute one half inch NPTF threads.

It is the desire of Rowe Manufacturing to provide a safe and economical device for the trucking industry. To help minimize down time and costly repairs associated with broken hoses. At the same time we want to abide by all DOT standards and regulations .
